Flexible Medical PCB Materials: 7 Substrates for ISO 10993 and USP Class VI
Pick the wrong flex material and your medical device fails sterilization, delaminates, and endangers patients. The right substrate prevents all three. Flexible medical PCBs use seven main substrates: polyimide, liquid crystal polymer, PET polyester, PTFE-based laminates, copper foil, biocompatible coatings, and high-temperature polyamide. Polyimide leads most designs for its thermal stability, chemical resistance, and flexibility. […]
